Benefits of technology

[0011] Therefore, it is one object of the present invention to provide a hair dyeing composition which induces rapid swelling of hair to expand the cortex, and as a result, effectively allows a colorant to infiltrate the cuticle, thereby shortening the dyeing time to reduce damage to the hair caused by chemical factors.
[0012] It is another object of the present invention to provide a hair dyeing composition that makes the hair wet and glossy and can protect the scalp by providing potent moisturizing effects to damaged and roughened hair after dyeing.
[0013] In accordance with one aspect of the present invention for achieving the above objects, there is provided a hair dyeing composition comprising a first functional agent containing an oxidative dye and an alkalizing agent and a second functional agent containing an oxidizing agent wherein the first functional agent further contains arginine for increasing the dyeing rate in an amount of 1.0-5.0% by weight, based on the weight of the first functional agent.
[0014] Preferably, the first functional agent further contains at least one additive selected from aloe vera gel, ceramide and hair keratin to protect the hair from damage. It is preferred that the first functional agent contains all of the additives. Preferably, the first functional agent contains 1.0˜10.0% by weight of aloe vera gel, 0.1˜1.0% by weight of ceramide and 0.3˜1.0% by weight of hair keratin, based on the weight of the first functional agent.

Problems solved by technology

Ammonia is associated with problems of unpleasant odor and irritation to parts of the human body, such as eyes.
However, since the alkalizing agent damages the hair and readily decomposes keratin proteins present on the hair surface, the hair feels bad to the touch after dyeing.
Particularly, since conventional hair dyeing agents using oxidative dyes require long periods of time for dyeing, the hair is exposed to alkalizing agents for a long time, causing great damage to the hair.

experimental example 1

[0039] Each of the first functional agents and each of the second functional agents prepared in Examples 1 to 6 and Comparative Example 1 to 6 were mixed in a ratio of 1:1. The mixtures were applied to the hair of five human subjects. After the time indicated in Table 4 lapsed, the mixtures were washed away with a shampoo, and then the hair was dried. The color development in the hairs was judged by ten panelists who have worked in beauty-related professions for more than 10 years and scored based on the following criteria. 5: excellent, 4: good, 3: average, 2: poor, 1: very poor. The average values are shown in Table 4 below.

[0042] Each of the first functional agents and each of the second functional agents prepared in Examples 1 to 6 and Comparative Example 1 to 6 were mixed in a ratio of 1:1. The mixtures were applied to the hair of five human subjects. Five minutes after application, the mixtures prepared in Examples 1 to 6 were washed away with a shampoo, and then the hairs were dried. Thirty minutes after application, the mixtures prepared in Comparative Examples 1 to 6 were washed away with a shampoo, and then the hairs were dried. The glossiness and dyeability of the hairs were visually observed and the fastness and moisturization of the hairs were judged by ten panelists who have worked in beauty-related professions for more than 10 years, and scored based on the following criteria. 5: excellent, 4: good, 3: average, 2: poor, 1: very poor.

Abstract

Disclosed herein is a hair dyeing composition. The composition induces swelling of hair to expand the cortex by the use of arginine, which is a constituent ingredient of hair, and as a result, effectively allows a colorant to infiltrate into the cuticle, thereby increasing the dyeing rate. Therefore, the composition can markedly decrease the dyeing time to 1˜5 minutes from 20˜30 minutes required in conventional hair dyeing compositions. In addition, the combined effects of aloe vera gel, ceramide and hair keratin enables prevention of damage to the hair during dyeing.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a hair dyeing composition, and more particularly to a hair dyeing composition which induces swelling of hair to expand the cortex by the use of arginine, which is a constituent amino acid of hair, and as a result, effectively allows a colorant to infiltrate into the cuticle, thereby shortening the dyeing time to reduce damage to the hair caused by chemical factors, and which can prevent damage of the hair due to the combined effects of aloe vera gel, ceramide and hair keratin during dyeing. [0003] 2. Description of the Related Art [0004] Hair dyeing is an artistic act of human desire to seek beauty by applying science to the color of natural hair. Hair dying is generally performed to return grey hair to an original hair color, alter an original hair color into more attracting color tone or brightness or exhibit hair decorative effects by coloring natural hair with an artificial color...
